The Parkes UHP Adapter facilitates the safe sampling of ultra high pressure liquids and gases into the Hastelloy cell of the Anton Paar DMA 4200 M. Similar in concept to the existing LPG Adapter, the UHP adapter extends the maximum pressure range to utilize the full 500 bar / 7250 psi range of the DMA 4200 M.
- Extremely simple connection to DMA 4200 M
- Simply swage or re-swage the two 1/8" tube fittings to the cell of the DMA 4200 M
- Low dead volume with easy cleaning/rinsing with included adapters
- Optional integrated pressure sensor for direct readings on the DMA 4200 M
- Pressure tested with ABSA certified documentation included
- Compact, rugged industrial design
Testing Procedure Summary
Note: this testing procedure does not purport to cover all safety and testing intricacies; and is intended for informational purposes only
- Ensure safety checks are completed in compliance with your company's internal policies
- Ensure inlet and outlet valves are closed on the UHP adapter and sample cylinder, and everything is connected properly
- Connect pressurized sample container to inlet of adapter
- Slowly open inlet valve
- If you have the integrated pressure sensor, you will see a reading on the instrument once the inlet valve is open
- If you have the external pressure port, you will see a reading on the gauge once the inlet valve is open
- Slowly open outlet valve to purge sample through the system
- Ensure outlet waste system is appropriately configured to accommodate the potentially high pressure sample flowing through the system, based on your specific setup
- Once sufficient sample has purged through the system, close the outlet valve
- At this point, optionally, you can apply additional back-end pressure to the sample to increase the pressure further or to account for any pressure drop that occurred during filling. This can be accomplished in a couple ways depending on the sample cylinder and pressure requirements. Please inquire if you have any questions.
- Once sufficient pressure stabilization has been reached, close the inlet valve to isolate the sample inside the DMA 4200 M cell
- At this point, optionally, you can bleed off pressure using the outlet valve to lower the testing pressure if it has been over pressured in the density cell.
- Begin the test as normal on the DMA 4200 M
